Rubber Coated Magnetic Locating Plate for Threaded Sockets - RD Series

2-in-1 Fixation and Recess Forming

The RD Series Rubber Coated Socket Magnet (also known as a schroefhuls magneet met rubber) is a highly efficient tool for the precast concrete industry. It is designed to securely anchor threaded transport sockets, lifting inserts, and connection sleeves to steel casting tables, while simultaneously acting as a protective recess former. Flexible Protection & Perfect Sealing Unlike standard bare-metal locating plates, the RD series encapsulates its powerful magnetic core in a durable rubber body. This rubber housing provides several distinct advantages:

1. Formwork Protection: It guarantees zero scratching or damage to your expensive steel casting tables when placing or sliding the magnet.
2. Slurry Seal: The flexible rubber compresses slightly against the steel formwork and around the base of the threaded socket, creating a watertight seal that prevents cement paste from leaking into the threads.
3. Clean Recess: It forms a smooth, shallow recess around the embedded socket in the final concrete element, which is often required for attaching lifting clutches or protective caps.

Versatile Interchangeable Threads Both the RD59 and RD76 models are highly adaptable, supporting a wide array of standard insert sizes. They are compatible with M10, M12, M16, M20, M24, and M30 threaded studs, making them a universal solution for your precast plant. Key Benefits:

• No Welding or Drilling: Preserves the lifespan of your steel formwork tables.
• Integrated Rubber Housing: Protects tables and ensures easy, clean demolding.
• Interchangeable System: Supports M10 through M30 threads on a single magnetic base.
• Flawless Accuracy: Keeps threaded inserts perfectly vertical during vibration and curing.

Technical Specifications

Model	Available Thread Sizes (M)	Pull-off Force
RD76	M10, M12, M16, M20, M24, M30	55 kg
RD59	M10, M12, M16, M20, M24, M30	80 kg

Note: Pull-off force is the vertical holding power measured on a clean, thick steel plate. The rubber housing slightly influences the magnetic grip, resulting in specific force ratings per model.

Application Instructions

1. Assemble: Select the correct threaded stud (M10-M30) and screw the lifting socket or insert hand-tight onto the RD magnet.
2. Position: Place the assembled unit onto the clean steel casting table. The magnetic grip will hold it firmly in place.
3. Pour: Pour and vibrate the concrete. The rubber base will prevent any slurry from entering the socket.
4. Demold: Once the concrete cures, lift the precast element. The magnet will detach from the steel table and remain in the concrete.
5. Remove: Unscrew the rubber magnetic plate from the socket. The rubber ensures it pops out of the concrete easily, leaving the threaded insert perfectly embedded with a clean surrounding recess.
